That is what I ended up doing but stumbled around a lot in the
process. I managed to destroy the mbr on the 108 install.
So now I have:
AVAILABLE DISK SELECTIONS:
0. c3d0 <DEFAULT cyl 362 alt 2 hd 255 sec 63>
/p...@0,0/pci-...@f/i...@0/c...@0,0
1. c3d1 <DEFAULT cyl 3260 alt 2 hd 255 sec 63>
/p...@0,0/pci-...@f/i...@0/cm
c3d0 holds 108
c3d1 holds 101b A fresh install.
So I have two problems I need to resolve to move on.
1) how to restore mbr on c3d0
2) how to move data on c3d0 to c3d1
1): I found some info about restoring with `installgrub' but having
trouble figuring out where to aim it. I tried:
installgrub -m /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c3d0s3
Checking with format/fdisk I made sure partition 3 was active as it
was originally.
Partition Status Type Start End Length %
========= ====== ============ ===== === ====== ===
1 Solaris2 1 364 364 5
2 Solaris2 365 728 364 5
3 Active Solaris2 729 1092 364 5
So boot would have some chance of working.
I haven't rebooted yet to see if it worked
So moving to:
2) again stumbling around here ... how to mount the rpool on c3d0
I tried a few things:
mkdir /rp1
mount /dev/dsk/c3d0s0 /rp1
r...@zfs:~# mount /dev/dsk/c3d0s0 /rp1
mount: /dev/dsk/c3d0s0 no such device
Of course the device appears to be present at that location.
ls -l /dev/dsk/c3d0s0:
# ls -l /dev/dsk/c3d0s0
lrwxrwxrwx 1 root root 48 2009-03-07 09:08 /dev/dsk/c3d0s0 ->
../../devices/p...@0,0/pci-...@f/i...@0/c...@0,0:a
So not sure how to get the install on c3d0 salvaged onto c3d1
